Course Update Information

September 03, 2014 (Wednesday). First day of this class.
September 03, 2014. MinGW C++ Installation Tutorial for Windows and Mac users.
September 03, 2014. Assignment 1 online, due on September 17 (Wednesday), 2014. Note of change: this submission (and the rest) should be submitted via an online Homework Submission Site. For retrieve your grade, please go to the Grade Retrieval Site. Details please visit the instructions of each assignment. We'll be conducting all class-related discussion on Piazza this term. Please login and enroll the class. The quicker you begin asking questions on Piazza (rather than via emails), the quicker you'll benefit from the collective knowledge of your classmates and instructors. We encourage you to ask questions when you're struggling to understand a concept - you can even do so anonymously.

Course Objectives

This course teaches the basic techniques to orgranize data in running programs. You will know about well-known data structures as listed in the Quick Syllabus. You will be able to

(1) implement these structures as classes in C++;
(2) determine which structures are appropriate in various situations;
(3) confidently learn new structures beyond what are presented in this class.

You will also learn part of object-oriented programming and software development methodology.

**Quick Syllabus**
To become a Data Structures Expert start by learning... Precondition/Postcondition specifications Time analysis techniques Container classes Pointers and dynamic arrays Linked lists Templates and iterators Stacks Queues Recursive thinking Trees Sorting and searching techniques Graphs

Textbook and References

Textbook: Data Structures and Other Objects Using C++, Third Edition, by Michael Main and Walter Savitch , Addison Wesley, softcover.

Supplements: The Code for the Book and the Corrections for the Text will be useful and can be found by clicking here.

References: Lots of good sample codes are found in CSc102's C++ How to Program by Dietel & Dietel, 3rd Ed., Prentice Hall 2001. This course involves some of C++ language details that could be found in this book.

Prerequisites

CSc103 (Introduction to Computing to CS and CpE Majors) and CSc104 (Discrete Mathematical Structure I). You should feel confident in your ability to design and implement simple programs using arrays and functions. As a rough guideline, all the materials before Chapter 5 (Pointers and Strings) of C++ How to Program by Dietel & Dietel are assumed to be understood. You should be familiar with some programming environment--either a PC or a Unix system.

Assignments and Grading

See syllabus above for the tentative timetable for a schedule. There will be six to seven programming assignments distributed roughly every two weeks (counted roughly 30% of your final grade). Several in-class small quizzes will add up to 10 % of your final grade. There will be three in-class exams (60% of your final grade). Dates of these exams will be determined in due times and announced beforehand.

Policies: Students may discuss ideas together. But since each student get credits for his or her submissions, all actual program code and written answers must be done individually by each student, and must not be shared.

Communications: I would like the course to run smoothly and enjoyably. Feel free to let me know what you find good and interesting about the course. Let me know as soon as possible about the reverse. You may see me in my office during my hours or send me messages by e-mail.

Computing Facilities

The language used for this class is ANSI Standard C++ as supported by today's available compilers. Variety of PC based (both Windows and Linux) C++ compilers are available, also publicly accessible at our Student Computer Labs.
